y is particularly adapted for the transportation of heavy objects,especially ashcans, up-and down flights of stairs.

. vided with means,

More specifically my invention resides in a handtruck which is soconstructed as to operate on level surfaces in the same manner as anordinary handtruck and which is pronormally so arranged as to provide noimpediment to the normal operation of the truck, for coacting with thetread of a flight of stairs for lifting or lowering the truck with itsload, such means being of a nature to relieve the operator of the mydevice;

. stud 5 (shown in Fig. 2 as the upper labor normally encountered inthis operation. This lifting and lowering means can, of course, be sodesigned as to still further relieve the operator.

The object of my invention is to improve the truck shown in my PatentNo. 1,839,317. The nature of these improvements and the further objectsand advantages of my invention will appear more fully from the followingdetailed discussion of the accompanying drawing in which:

Fig. 1 is a front elevation of my device with the lifting means out ofoperative position;

Fig. 2 is a detail of part of the frame of Fig. 3'is a plan view of mydevice in the position shown in Fig. 1; i

Fig. 4 is a side elevation of my device at the beginning ofthe liftingoperation; and

Fig. 5 is a side elevation of my device at the end of the liftingoperation. Referring to the drawing in detail 1 represents the framewhich is made of a metal rod or tube of any cross sectional shape whichis i bent to form the nose 2'and cradle 3 of the truck. This bending isdone in such a way as to leave one of the free ends of the rod or tubelonger than the other. At the upper end of the cradle the free ends ofthe rod or r tube are arranged in juxtaposition to each other, the longfree end being bent to form a handle 4. The free ends meet below saidhandle and overlap in such a manner that either of them can be turned-upto forrfn a ree invention relates to a handtruck which 1532. Seria1 n. 58,10

When secured by the stud the lifting rod is heldtightly in position by reason of the fact that the' spring 9 must beslightly extended in order to permit the engagement of the stud by therod 8.

The operator can then kick the rod 8 intoreengagement with the stud 12 and proceed without impediment along thelevel surface. This construction offers the important ad vantage overthe construction shown in my aforesaid patent that when the lifting rodis out of operation it is not necessary to keep the spring under fulltension whereby the life of the spring 7 Whereas in my priorconstruction I secured the lifting rod out of position with a sepa ratelocking member, I secure the lifting rod in my present construction outof operating position by a slight tension of the spring itself. oreover,my present construction eliminates the need for brackets arranged on thebody of the truck to prevent the free end is considerably prolonged.

of the lifting rod from swinging when said rod is out of operativeposition.

Having thus described the nature and objects of my invention andillustrated a specific embodiment of the same what I claim as new anddesire to secure by Letters Patent is:

1. In a handtruck having a frame with an axle at its lower end, a pairof wheels mounted 011 the axle, a lever connected to the upper part ofthe frame and a lifting rod having one end connected to the lever andthe other end adapted to coact with the tread of a stair way, means forimparting a lifting force to said frame comprising a spring having oneend attached to said lifting rod and the other end attached to the bodyof said truck, and means for securing the said lifting rod out ofoperating position comprising a stud ar ranged on the bodyof said truckand adapted to coact with said rod in such a manner that when the rod isplaced in engagement with said stud it is held in that position by thetension of said spring.

2. In a handtruck having a frame with an axle at its lower end, a pairof wheels mounted on the axle, a lever connected to the upper part ofthe frame and a lifting rod having one end connected to the lever andthe other end adapted to coact with the tread of a stairway, a springhaving one end attached to a predetermined point on said rod and theother end attached to the frame of said truck near its axle and a studprojecting from the body of said truck at such apoint that when thelifting rod is swung into the body of said truck out of operatingposition it can be placed in engagement with said stud only by placingsaid spring under a slight tension suflicient to hold said rod inengagement with said stud.

8. In a handtruck, in combination, a frame constructed of a single rodbent to form the nose of the truck, the cradle and the handle, the freeends of said rod meeting at a point below the handle of said truck andone of said
